OEM Countershaft 2nd Gear AZ2210030032/8 for HOWO Truck
As an essential drivetrain component, the Countershaft Second Gear with OEM number AZ2210030032/8 plays a critical role in power transfer efficiency for HOWO heavy-duty trucks. This precision-engineered gear forms part of the transmission system responsible for delivering optimal torque conversion during gear shifts. Manufactured to exacting specifications, it ensures seamless integration with other transmission components in HOWO trucks, guaranteeing the power consistency needed for challenging hauls across diverse terrains. Surface-hardened through advanced heat treatment processes, this gear exhibits remarkable resistance to deformation under extreme pressure conditions.
Enhanced Power Transfer Capability
The AZ2210030032/8 gear features helical tooth geometry optimized for noise reduction and load distribution. Unlike standard gears, this OEM-specified component minimizes vibration transmission throughout the drivetrain system. The precisely calculated helix angle allows for gradual engagement between mating components, reducing shock loading during aggressive shifts. This design translates directly into longer service intervals for HOWO operators.
Material Durability Advantages
Crafted from high-grade chromium-molybdenum alloy steel, this countershaft second gear achieves the perfect balance between toughness and wear resistance. The AZ2210030032/8 designation guarantees material traceability throughout the manufacturing process. Unique carbide enrichment at the tooth surface level enhances pitting resistance – a common failure point in lower-quality transmission components.
Precision Engineering Specifications
Every AZ2210030032/8 gear undergoes coordinate-measuring machine (CMM) verification post-machining to ensure dimensional compliance within 0.005mm tolerance bands. This attention to dimensional precision guarantees correct meshing depth with mating components throughout the transmission assembly. The precisely ground tooth profile eliminates localized stress points that can lead to premature gear fatigue.
Heat Treatment Superiority
The AZ2210030032/8 part undergoes proprietary thermal cycling that develops an optimal hardness gradient from surface to core. Surface hardness reaches 58-62 HRC to resist abrasion while maintaining a tough, shock-absorbent core at 35-40 HRC. This controlled depth hardening prevents surface spalling under cyclical loading conditions typical in heavy-duty truck operations.
Quality Validation Process
Each production batch of AZ2210030032/8 gears undergoes randomized destructive testing where sample components are subjected to accelerated lifetime simulations. This validation includes torsion strength testing, surface durability analysis, and fatigue resistance verification. Test results consistently exceed SAE J404 standards, ensuring reliable performance throughout the gear’s service life.
Application-Specific Design Advantages
Engineered specifically for HOWO transmission configurations, the AZ2210030032/8 countershaft gear maintains correct axial positioning through precision-machined shoulders and snap ring grooves. This specialized design prevents the axial drift that can cause transmission noise or catastrophic failure in generic replacement parts.
Maintenance Optimization Features
The AZ2210030032/8 gear incorporates unique oil channel geometry promoting superior lubricant distribution across critical contact surfaces. Chamfered edges at oil entry points facilitate enhanced splash lubrication while the micro-textured tooth surface retains protective oil film under high-pressure conditions.
Counterfeit Prevention Measures
Original AZ2210030032/8 components feature permanent laser-etched identification markers and anti-counterfeiting holograms. These security measures protect HOWO operators from substandard replicas that fail to meet material specifications and dimensional tolerances.
Logistical Availability & Support
With dedicated inventory management for HOWO drivetrain components, AZ2210030032/8 gears maintain constant stock availability across global distribution centers. Region-specific shipping protocols ensure timely delivery with custom clearance pre-processing to minimize installation downtime.
Installation Compatibility Assurance
Direct replacement for factory-original components, the AZ2210030032/8 requires no modification or supplemental shimming during transmission reassembly. Installation kits include OEM-specified preload spacers and selective washers to restore exact factory tolerances without specialized tooling.
Environmental Compliance Standards
All AZ2210030032/8 production processes comply with RoHS and REACH regulations. Surface treatments utilize cadmium-free coatings while manufacturing waste streams undergo specialized metal reclamation processes. Packaging incorporates biodegradable materials without compromising component protection.
